Dog allergies are a common form of allergy in the United States. According to the American Academy of Allergy, Asthma and Immunology (AAAAI), nearly 10 million pet owners are allergic to their animals.

Dogs can cause allergic reactions in people with allergies specific to dogs and in people with allergic asthma, a condition in which asthma symptoms are triggered by an allergic reaction.

Symptoms of allergic reactions to dogs include sneezing, itchy and watery eyes, coughing, wheezing and difficulty breathing. In rare circumstances, dog allergies cause the severe and potentially life-threatening allergic reaction known as anaphylaxis. Allergic reactions may be triggered by proteins in dog dander (small flakes of skin), as well as proteins in dog saliva, blood or urine.

For most allergies, the main form of treatment is avoidance – completely avoiding contact with the allergen to prevent an allergic reaction from occurring. For dog owners with allergies, avoidance is not easy. However, there are options that can lessen or relieve symptoms. These include medications such as antihistamines and decongestants, as well as allergy shots (immunotherapy).

Many pet owners will be able to control their allergies without taking the drastic measure of finding a new home for their dog. However, individuals with significant dog allergies, or dog allergies that trigger asthma, must remove their dogs.
